Rechargeable battery
Bosch sells some cordless power tools without a re-
chargeable battery. You can tell whether a rechargeable bat-
tery is included with the power tool by looking at the pack-
aging.
Charging the battery
u Use only the chargers listed in the technical data. Only
these chargers are matched to the lithium-ion battery of
your power tool.
Note: Lithium-ion rechargeable batteries are supplied par-
tially charged according to international transport regula-
tions. To ensure full rechargeable battery capacity, fully
charge the rechargeable battery before using your tool for
the first time.
Inserting the Battery
Push the charged battery into the battery holder until it
clicks into place.
Removing the Battery
To remove the rechargeable battery, press the battery re-
lease button and pull the battery out. Do not use force to do
this.
Battery charge indicator
The battery charge indicator indicates the state of charge for
a few seconds when the on/off switch is half or fully pressed.
LED Capacity
3×continuous green light 75–100%
2×continuous green light 40–75%
1×continuous green light 15–40%
1×slowly flashing green light 0–15%
The three LEDs in the battery charge indicator and the pres-
sure gauge lighting flash simultaneously when the temperat-
ure of the rechargeable battery is outside the operating tem-
perature range and/or the overload protection has been
triggered.
Recommendations for Optimal Handling of the
Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50°C. Do not leave the battery in your car in the summer, for
example.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
Mounting and Operation
Select the adapter best suited to the intended application:
– Valve adapter(13), e.g. for many bike valves.
– Ball needle adapter(14), e.g. for footballs.
– Volume adapter(12), for small beach items or sporting
goods, e.g. beach balls.
For standard car tyre valves (sometimes also used on bikes),
no adapter is required.
